SHEET-DELIVERY MECHANISM FOR PRINTING-PBESSES.

Specification of Letters Patent.

' Application filed June 20, 1916. Serial No. 104,732.

Be it known that I, HowARo M. BARBER, a citizenof the United'States, and resident of Stonington, in the county of New Lon don and State of Connecticut, have invented I a new zand useful Improvement in Sheet-Delivery Mechanism for Printing-Presses, 0f

which the following is a: specification.

In printing-presses where very wide webs are printed, it has been found difficult to accurately cut the web transversely by asingle cutting mechanism, as, for instance,

by coacting rotary cutters; for the reason that it is almost impossible to keep the cutter blades from sagging. It has also been necessary to materially sloW down the travel of the wide web to permit it to be cut as it passes through said cutters.

The principal object of this invention is to provide means for slitting the wide web into two or more narrow webs, to provide sepa "ratesheet cutting means for each narrow web, groups of sheets cut from said narrow webs,

and toprovide means for collecting fold said groups of sheets and deliver them.

. The invention more particularly includes the provision of means for passing the narrow webs and the sheets cut therefrom, collected and folded, through the machine without lateral movement, the cutting devices for thenarrow webs being of less length than the wide web and being arranged in differ- 1 is represented in the accompanying drawenttransjverse planes, the collecting, folding and delivery mechanisms being of the full-width of the wide web.

A practical embodiment of the invention ings, in which,

Figure 1 is a view in top plan of so much of a sheet cutting, collecting and folding machine as will give a clear understanding I of the invention.

Fig. 2 is a vertical longitudinal section through the same.

Fig. 3 is a detail view of the gearing for driving the several'parts.

showing the ro- Fig. 4 is adeta-il section collecting,

tary carriers for transferring,

folding and deliveringthe sheets, and

Fig. 5 is a detail section showing certain of the operatingcams not shown in Fig. 2.

The wide web 1 is passed over a slitting roll 2-,'where it is slit longitu-dinally of its travel into narrow webs, in the, present instance two narrow webs, by a slitting disk 3.

The two narrow webs 4 and 5 then pass between the rolls 6 and 7, and the narrow web 4 is passed rearwardly and around the roll 8, while the narrow web' 5 is 'passed forwardly and around the roll 9.

Two pairs of coacting rotary cutters 10', 11 and 12, 13, are arranged indifferent transverse planes, the cutters 10, 11, being used to cut sheets from the narrow web 4 and the cutters 12, 13, being used to cut sheets from the narrow web 5. These cutters are of less length than the width of the wide web 1, and are located in difierent transverse planes.

Means are provided for passing the narrow web 4 through the rotary cutters 10, 11, which means in the present instance, is shown as an endless carrier in which the side chains 14, whichpass over the upper and lower sprockets 15, 16, are provided with side grippers 17 carried at intervals along the same, and arranged to grasp the side edges of the narrow web 4 before the web reaches the rotary cutters 10, 11, and'carry the web through said rotary cutters. Similarly an endless carrier comprising the side chains 19, passing over the pairs of upper and lower sprockets 20, 21, and having the side grippers 22, is provided for carrying the narrow web 5 through the rotary cutters 12, 13.

A rotary sheet carrier 24 is provided with two sets of grippers 25 arranged to transfer the sheets cut from the narrow web 5 to successive sets of grippers 26 on the rotary sheet collecting and folding carrier 27. In the present instance the carrier 27 is shown as being provided with three collecting surfaces and three'sets of grippers 26. Three sets of grippers 28 on the rotary sheet collecting and folding carrier 27, are arranged in alinement with the three sets of grippers 26, which sets of grippers 28 are arranged in the plane of the narrow web 4 and are operated to take the heads of the sheets cut from the narrow web 4.

A fixed cam 29 is arranged to control the operation of the two sets of grippers 25 on the rotary carrier 24, for grasping the sheet cut from the narrow web 5, and for releasing the head of said sheet as it is transferred to Patented Apr. 8, 1919. p

its set of'grippers 26 on the rotary carrier 27. A fixed cam 30 is arranged in position ing and delivery carrier to be hereinafter described.

A movable cam 32 controlled by a rotary cam 33, is arranged in position to control the operation of the grippers 26, to permit the folding ofi' of the collected group of two sheets, in the present instance, cut from the narrow web 5. A movable cam 34 controlled by the rotary cam 35, is arranged to control the operation of the grippers 28 to permit the folding off of a collected group of two sheets cut from the narrow web 4;

The rotary carrier 27 is shown as provided with three folding blades 36 extending the full width of the wide web and locatedintermediate the alined sets of grippers 26, 27, which folding blades are arranged to coact with the sets of floating folding jaws 37 carried by the rotary sheet folding and delivery carrier 38, which also extends the full width of the wide web.

floating folding jaws at the time of the folding operation, and a fixed cam 40 is arranged in position to control the operation of the floating folding jaws to deliver the folded groups of sheets upon a suitable surface, as, for instance, the endless delivery carrier 41; The usual cam 42 is provided for controlling the floatingof the folding jaws in the wel known manner.

The side frames of the machine are de' noted by 43, 44 and the intermediate short longitudinal frames by 45, 46. The rotary cutters 10 and 11 and the means for passing the narrow web 4 through the cutters are mounted between the side frames 44 and the intermediate frame 45. The rotary cutters 12 and 13 and the means for passing the narrow web 5 through thecutters are 'ar ranged between the side frame 43 and the intermediate frame 46, thus locating the cutters for the two narrow webs in different transverse planes The rolls 2, 6 and 7 extend the full width of the wide web and the rolls 8 and 9' extend preferably only the width of their respectivewebs 4 and 5. The grippers 25 of the rotary transfer carrier 24, extend preferably only the width and in the plane of the narrow web 5, while the rotary carriers 27 and 38 and the endless delivery carrler 41 preferably extend the full width A fixed cam 39 isprovided for controlling the operation of the driven throughthe gears 49, 50, 51, 52, 53,

54, 55. The rotary cutters 10, 11, are driven through the gears 56, 57, 58. The. endless carrier for feeding the web 4' through the cutters 10,11; is driven from the gear 59.

The rotary carriers 27 and 38 are driven through the gears 60, 61, 62. The rotary carrier 24' is drivenjfrom the carrier 27,

through the gears 61, 63. The rotary cutters '12, 13, are driven through thegears 64, 65. The endless carrier for pa'ssing'the narrow web 5'throug'h the rotary cutters 12, 13 is driven through the gear 66. The-roll 9 is driven through the gears 67,68, 69.

From the above description it will be seen that by providing a separate cutting mechanism for each narrow web, the cutting mechanisms are kept within a convenient length for accurate and'rapid severing of the'sheets from the narrow webs. j

It will also beseen that the narrow webs and the sheets cut therefrom, collected, and

folded," may be passed through the machine without lateral movement.

It is evidentthat slight changes may be resorted to in'the form, construction and arrangementof the several parts without departing from the spirit and scope of my invention; hence I do not wishto limit myself strictly to the structure herein shown and described, but

What I claim is: w
